Thank you both for your replies. I forwarded them to her. (She will see what a wonderful group this is!) I have been trying to get her to invest in a nebulizer and also a spritzer for the nose. Sara, I assume the dried olive leaf is in capsule form?
The weather at the moment in Toronto is wind, rain, snow and cold so I hope someone in the family can venture out to the health food store if she decides to try your suggestions.
